Implantation of a Flexible Silicone Iris Diaphragm to Prevent Silicone Keratopathy

Bernd Kirchhof
Indications for a closed iris diaphragm are eye that require a permanent (PVR, aqueous insufficiency) silicone oil tamponade, but are at risk of silicone keratopathy (Aniridia, Aphakia). A former version with a central opening is no longer used, because all indications can be served with the closed flexible type.
